Summary 1. A distribution study, in the system NH4Cl-CoCl2-H2O at 0°, showed that, with decreasing concentration of cobalt in the solution from 2.3 x 10−1 to 4.7 x 10−6 M, the distribution coefficient fell from 0.16 to 0.018. This showed the existence of a lower limit of formation in this system at 0°. 2. Investigation of the same system at 57° showed that, with changing cobalt concentration from 1.2 x 10−1 to 1.2 x 10−6 M, the distribution coefficient remained constant with a mean value of 0.36. 3. In the system with cobalt, depending on the conditions of crystallization, the distribution of the microcomponent between the solid and liquid phases can occur in a way characteristic of anomalous mixed crystals or of true mixed crystals.
